Well I just got new strings I put them on but now when i hit my A string open it buzzes like its hitting a fret,but when I hold the nut on the A string and hit the string there is no buzzing the other strings sound great.Its just the A string.My brothers bass does it too.Do you think it has to do with how he put them on? 
not sure if this is the right section >_<
